[Five-choice speech discrimination test].
In order to overcome defects of dictation method, a new 5-choice method introduced into Japanese mono syllables discrimination test. A new 20-items mono syllables list was developed on the principle of equal probability of the Japanese consonant phonetics, instead of the present mono syllable frequencies among the 100 Japanese mono syllables. The choice items for the each stimulus syllables were selected on the analysis of perceptual confusions data among hard of hearing persons. Comparison of discrimination scores and consonant confusions of the dictation method speech test and 5-choice method revealed that the two tests were parallel with some advantages of easiness of test procedure, and easiness and objectivity of scoring on the side of 5-choice method.
